Subject: [GIT PULL] tracing: Minor fixes


Linus,

This includes three minor fixes, mostly due to cut-and-paste issues.

The first is a cut and paste issue that changed the amount of stack
to skip when tracing a stack dump from 0 to 6, which basically made
the stack disappear for small stack traces.

The second fix is just removing an unused field in a struct that is no
longer used, and currently just wastes space.

The third is another cut-and-paste fix that had a tracepoint recording
the wrong field (it was recording the previous field a second time).


Please pull the latest trace-v4.5-rc1 tree, which can be found at:
